    i have a 4" lift on my 90 suburban right now and in the future i would like to go up to a 6-8" lift. i think ive read on here that the most you can get away with the stock driveshafts is 5". are there companies that sell driveshafts already extended, or do i need to send mine out? what are good companies to use? and the most important question- how much should both drive shaft be extended. thanks for any help.

    That pic isn't too good. Are there any splines showing? I had my front extended 2" with a 5" lift. I really could have gotten away with 1", but I wanted the option to go bigger later.

    watch that drive shaft being TOO long, if it runs out of compressiopn it can spell bad things for your t case.

    You really need to measure what lengths you need at full droop and compression, and check your stock shaft to see if it will work. I wheeled the piss out of mine quite a few times and she never bound up on me. Like I said, 1" was good for me but I planned to lift it another 1-2" so I went with a 2", but I also had more travel in my slip yoke to accomodate it.

    What kind of transmission/transfer case do you have. I had the sm465/np241.If you have the TH400/208 it won't work because the front driveshaft will be too short & the rear too long

    well when i looked online, it seems that the sm465 is a manual transmission, and since mine is an auto id say they wont fit. thanks anyways.
